MACH(Macro Array CMOSHigh-density)器件是美国AMD公司推出的新一代复杂可编程逻辑器件(CPLD).它具有高性能、高密度、高可靠性、延时可预测、编程方便等优点,是集成中小规模数字电路的理想选择.MACH器件共有MACH1～5五大系列,几十个品种.其中MACH1、2系列为32～128宏单元,通过中央矩阵互连多个PAL块的结构,可以方便地将使用GAL或PAL以及中小规模数字电路的设计直接移植到这种器件中.MAHC 3、4系列为96～256个宏单元,通过输入、输出和中央矩阵互连多个PAL块结构.这种结构在MACH1、2的基础上增强了用户锁脚的灵活性,提高了器件的布通率.MACH5为AMD
MACH (Macro Array CMOSHigh-density) device is a new generation of complex programmable logic device (CPLD) introduced by AMD in the United States.It has the advantages of high performance, high density, high reliability, predictable delay and convenient programming, Small and medium-sized digital circuits ideal .MACH devices a total of MACH1 ~ 5 five series, dozens of varieties. MACH1,2 series of 32 to 128 macrocells, through the central matrix interconnection of multiple PAL block structure, you can easily Ports directly into this device using GAL or PAL and designs for small and medium-scale digital circuits. The MAHC 3,4 series are 96 to 256 macrocells interconnecting multiple PAL block structures through inputs, outputs and a central matrix. On the basis of MACH1, 2, users have increased the flexibility of the user’s locking foot and improved the fabric penetration rate. MACH5 is an AMD
